2.4 V CW LASER DIODE DRIVER
FEATURES
BLOCK DIAGRAM
GND
+2.4..+6 V
CW operation up to 90 mA from 2.4 to 6 V supply voltage
Rapid soft start after power-on typical within 70 µs
Simple power adjustment via the external resistor
Control loop accuracy better than 1% with changes in
temperature, supply voltage and load current
Integrated reverse polarity protection for the iC and laser diode
Strong suppression of transients with very small external
capacitors; integrated flyback path
Permanent shutdown with excessive temperature and
overcurrent (i.e. if the laser diode is damaged or the feedback
current path fails)
Two feedback inputs permit all current LD types to be used
(N/P/M configurations)
Modulation via the feedback inputs is possible
Wide monitor current range from 10 µA to 2.5 mA
iC-WK with additional spike detection at monitor input MDA
